[The information value of the clinical data related to the vital prognosis in severe combined trauma].
Data are reported on a study of the informative value of ten clinical and laboratory parameters, which have a bearing on the vital prognosis of severe combined trauma. The presentation is part of a more comprehensive study, aimed at creating an expert system for prognosticating this type of pathology. Case material from the Clinic of Anesthesiology, Resuscitation and Intensive Treatment at the "Pirogov" Emergency Hospital in Sofia was used (1986-1988). Included in the study were 455 patients with severe combined traumatic injuries, of whom 210 died and 245 survived. The following methods were used for quantitative assessment of the informative value: for determining the descriptive informative value--informative criterion by Mel'nikov and informative criterion by Bykhovskiĭ [correction of Bihovski]; for the distributing informative value--the method of Kulback and modification of this method, as described by Genkin-Gubler. Simultaneous use of all four methods allowed to precise the values being obtained and to perform with maximal exactness the intervals relevant to the prognosis. This furnished the opportunity to distribute the individual parameters in highly informative groups, designated for entrance to the projected expert system.
